摘要： Cellular signals or other wireless signals/messages are introduced into a building or to an outside location by transmitting packets corresponding to those signals over a data network and low cost cables to designated locations within the data network. Once the designated packets containing the signals reach the destination, they are then broadcast over the air to a terminal capable of receiving the wireless message. In a first embodiment, an in-building gigabit Ethernet network, such as that currently existing presently in many buildings, is used to distribute radio signals indoors. Instead of transmitting the radio signals over the air from a repeater connected to a base station, coded baseband signals generated by the coding processor (e.g., a CDMA Modem Unit) in the base station are packetized and sent over the Ethernet network to radio processing equipment and antennas distributed throughout the building. The radio processing equipment strips the packet headers from the baseband signal packets so those signals can be broadcast via the antennas to one or more mobile terminals. Additionally, hard handoff is employable upon entering a building using specifically configured pilot signals.

摘要： In an example embodiment of the present invention, the method includes creating a plurality of data packets. Each data packet in the plurality of data packets includes a plurality of coded cellular signals. The plurality of data packets are sent over a data network associated with at least one sector served by a plurality of transceivers, and at least one of the plurality of transceivers broadcasts the data packets. A location of a mobile station is determined based on received multi-paths associated with response from the mobile station to broadcast of at least one of the plurality of data packets.

摘要： A wireless communication technique provides mobility for a mobile station (52) to communicate with an overlay network device (40), which is within a coverage area (34) of an underlay network device (24), when the mobile station (52) is within a coverage area (42) of both devices. The overlay network device (40) broadcasts at least two downlink channels. A cell code (e.g., a scrambling code or pseudo noise offset) of a first one of the downlink channels identifies an overlay network device (40) exclusively. The mobile station (52) can detect the first downlink channel responsive to an indication of the exclusive cell code from the underlay network device. A second one of the downlink channels allows for subsequent, ongoing communications between the mobile station and the overlay network device.

摘要： A digital detector processes at least one received digital signal to generate a squared signal, encodes the squared signal, applies first and second portions of the encoded signal to a multiplier and a look-up element, respectively, and processes outputs of the multiplier and look-up element to generate a detector output signal representative of a power level of the received digital signal. In an illustrative embodiment, the digital detector is configured so as to exhibit a waveform dependence substantially the same as that of an analog logarithmic amplifier detector. The digital detector and analog logarithmic amplifier detector are utilizable in a closed-loop gain control arrangement for providing a desired gain for a signal path of a base station transmitter in a wireless communication system.
